    the only thing we (jointly)could think of,have you washed out the crankcase breather(if fitted)
    follow the hose from the inlet manifold to the side of the block,if its blocked you could have a sweet/oily plastic type smell.or if you havnt got a block breather the small hose to the top of the cam cover,to the inlet manifold.also look at the air filter to see if its oily.....
    good luck..

Code 16518 on mk4 golf


Can't by pass as oxygen sensors control your fuel

I suspect your exhaust converter has failed & the car has
been running rich for years & ruined it

Wouldn't your repair guy be able to solve all your issues,
after all you were at a shop for some work

Sounds like they sold some service instead of diagnosing
the reason you were there

Hello: Code 420 normally indicates a catalytic converter is operating below 60% efficiency. You need to take your car to another shop and request a COMPLETE diagnosis not a dart board guess.

Po420 code monte carlo ls 2001


PO420 code is for catalyst system efficiency below threshold (bank 1) Usually it means that it is time for a new catalytic converter on bank number 1. Cylinder bank number 1 is always the bank with the number 1 spark plug in it.

Golf gti left rear door locking system


it is probably your door lock has gone into safe mode.you need a new door lock.try using the lock/unlock button on your remote or on the drivers door button and gently tap the door handle with your hand while pressing the lock/unlock button,carefull not to dent your car.if that does not work,try disconnecting the cars battery for a few minutes,but note the vehicle might pick up fault codes which need a diagnostic machine to clear...good luck
